What is Adalat CC?
Adalat CC (nifedipine) belongs to a group of drugs called calcium channel blockers. It works by relaxing the muscles of your heart and blood vessels.
Adalat CC is used to treat hypertension (high blood pressure) and angina (chest pain).
Adalat CC may also be used for purposes not listed in this medication guide.
You should not use Adalat CC if you have severe coronary artery disease, or if you have had a heart attack within the past 2 weeks.
Before taking Adalat CC, tell your doctor if you have kidney or liver disease, a blockage in your digestive tract (stomach or intestines), a history of stomach surgery, coronary artery disease, underactive thyroid, diabetes, or congestive heart failure.
If you need surgery, tell the surgeon ahead of time that you are using Adalat CC. You may need to stop using the medicine for a short time.
Do not stop taking Adalat CC without first talking to your doctor, even if you feel fine. Stopping suddenly may make your condition worse. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
Before taking this medicine
You should not use Adalat CC if you are allergic to nifedipine, if you have severe coronary artery disease, or if you have had a heart attack within the past 2 weeks.
To make sure Adalat CC is safe for you, tell your doctor if you have:
severe COPD (chronic obstructive pulmonary disease);
congestive heart failure; or
if you take other medications, especially an antibiotic or antifungal medicine, an antidepressant, heart or blood pressure medicine, or drugs to treat HIV/AIDS or hepatitis C.
It is not known whether Adalat CC will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
Nifedipine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I take Adalat CC?
Take Adalat CC exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take Adalat CC extended-release tablets on an empty stomach.
Do not crush, chew, or break an extended-release Adalat CC tablet. Swallow it whole.
Your blood pressure will need to be checked often and you may need other blood tests at your doctor's office.
If you need surgery, tell the surgeon ahead of time that you are using Adalat CC. You may need to stop using the medicine at least 36 hours before surgery.
You may have very low blood pressure while taking this medication. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual.
If you are also taking a beta-blocker (atenolol, carvedilol, labetalol, metoprolol, nadolol, nebivolol, propranolol, sotalol, and others) you should not stop using the beta-blocker suddenly or you could have serious heart problems that will not be prevented by Adalat CC. Follow your doctor's instructions about tapering your beta-blocker dose.
You should not stop using Adalat CC suddenly. Stopping suddenly may make your condition worse.
If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
